in2extRemes: Into the R package extRemes. Extreme value analysis for weather and climate applications

The aim of in2extRemes and this document is to facilitate a shortened learning curve for performing statistical (univariate) extreme value analysis (EVA). Originally, the graphical user interfaces (windows) were provided by extRemes (versions less than 2.0), which predominantly interfaced to the R package ismev.

Now, however, extRemes greater than or equal to 2.0 is a command-line (no windows) EVA software package similar to ismev, but with considerably more functionality. A brief overview of EVA is provided, as well as a tutorial on how to install, start and use in2extRemes. Knowledge of R is not required to use in2extRemes apart from a few minor commands that are detailed here.
